I keep mine on a twice a week schedule until there 600 grams (tues&fri). If they don't eat one of those days I don't sweat it, but they almost always do. But all my ball pythons that weigh over 600 grams get fed every friday. Its not a rule but it's what works for me.

At that weight right now your little one should have no problem slamming rat pups. That's what I feed mine that are close to her size.

Hope this helps
